Hi,


Hi!

"No service implements the interface XXX" means you're trying to inject
a dependency of type XXX in some service or object created by
ObjectLocator/Registry.autobuild(). The class you're editing in
BeanEditForm, Tanken, probably has constructors other than a no-arg one
and you're leaving the instantiation of Tanken to
BeanEditForm/BeanEditor, which does that by calling
ObjectLocator.autobuild(), which takes the constructor with the longest
list of parameters then considers them as dependencies (services) to
inject.

Here's my proposed fix: instantiate the object yourself in your page:

void onPrepare() {
 if (tanken == null) {
 tanken = new Tanken();
 }
}

The 'prepare' event is triggered just before a Form is rendered
(BeanEditForm uses this component internally) and also just before a
form submission is handled, triggering the 'validate', 'success' and
'failure' events as needed.



You saved my day. I think, i never would find to change setupRender to 
onPrepare. The other T5 project got onPrepare ...


Thanks a lot!

Use BeanEditForm "prepare" event to instantiate your Celebrity instead
of letting BeanEditForm to do that.

你把缺省的构造去掉就可以了
否则T5IoC会去自动进行参数注入 注入的参数就会去找实现的service 找不到就报这个错误了

While I'm using BeanEditForm component from T5.0.18, it throws an
error says "no servicie implements java.util.Date". My code is quite
simple.



and Celebrity is just a POJO which has an constructor like "public
Celebrity(String firstName, String lastName,Date dateOfBirth)". I'm a
newbie and can't find any clue due to the poor documentation of
Tapestry. Could someone give me a hint or tell me which doc I should
read. Thanks a lot.
